- There are no minimum hematological parameter requirements prior to the first two cycles, as patients with AML and myelodysplastic syndrome (MDS) are understood to have low absolute neutrophil count (ANC) and platelet counts when the disease is active. However, patients with white blood cell count (WBC) greater than 30,000 will receive hydroxyurea to reduce the WBC count to below 30,000 at which point they may begin treatment.
